Well then why not consider an 845? You can get prime examples for less than equally the same 3566’s.
The first run MPC ones were even called Limited.
.45 acp ammo is a whole lot easier to get, (well sorta now,) and I can attest to the incredible form, fit, function and accuracy of the 845. I’d like to say it’s my favorite S&W pistol I have but then I start thinking. Hard to have just one favorite depending on what it’s use is.
